Conference publicationsCurves Approximation by the Mulityfocal Lemniscates on a Complex PlaneThe task of analytical approximation of the point-by-point given closed curves by the multi-focal lemniscates on a complex plane is solved. The curve to be approximated is represented thus by a finite set of focus points inside a curve. The method for construction of approximating lemniscate as a level line of a complex polynomial modulus by mapping the curve to be approximated onto phase circle is developed and investigated |
